Using failure modes and effects analysis (FMEA) to risk assessment pipelines of petroleum products

The risk assessment methods and different methodologies provided that each of them had complex or simplistic approach to the issues. The practical steps to implement a practical and comprehensive approach to risk assessment and analysis of potential risks derived from FMEA method is presented in a way that is easily the implementation of. This study aimed to determine failure modes and effects (FMEA) was performed in oil pipelines. This study was cross-sectional and functional expertise of highly qualified individuals. The failure modes were analyzed pipelines. Team scores related to severity (S), probability (L), detection (D) failure modes according to certain tables, were identified. Risk Priority Number (RPN) RPN = S × O × D was calculated as the product. The results showed that the RPN of line rupture caused by Sabotage (wars, bombing, terrorist attacks)is equal to 560, vapors and gases from welding due to the lack of proper masks with RPN=60are the highest and lowest risk of their allocation. For the purposes of continuous improvement, in coordination with senior management and statistical analysis, RPNs up to 350 was determined as an acceptance criterion. Finally, the team members to reduce risk, concluded that control measures, such as regular inspections of the pipeline to reduce the damage caused by an external force to the pipe and also redirect pipeline routes that is possible to reduce the risk of landslides tube rupture is the high priority.
